| Abstract |
This study emphasizes the correlation between the climate characteristics and annual energy demand in the region where passive houses are constructed, by analyzing the annual heating energy demand according to local climatic conditions for domestic passive houses (E+Green Home) using the PHPP simulation program. 7 regions of Korea were targets of the simulation (Yongin, Paju, Seoul, Andong, Kwangju, Busan, and Tongyoung). The heat energy required declined by about 16.7% when the outdoor temperature rises by an average of 1 ℃ and the heating load declined 1.4 W/㎡ . This corresponds to about 14% of the maximum heating load, which is 10 W/㎡, that is required by Passive house. Also, as a result of comparing Yongin (16.8 kWh/㎡·yr) and Tongyoung (3.6 kWh/㎡·yr), the yearly heat energy required showed about 4.7 times difference. Moreover, to reflect in details about the characteristics of the region climate in the building energy saving design criteria, there is a need to separate the current 3 regions into a minimum of at least more than 7 regions. From the results above, it is found that the local climatic conditions should certainly be taken into account when buildings at a level of passive houses are designed. Besides, since the annual heating energy demand for a passive house varies greatly with the local climate characteristics, the passive house design guidelines for insulation and ventilation performance depending on the region should be presented. |
